Captive. The Franssisi Four Chronicles, #2

Do you like it steamy, but are not a fan of Romance? Do you like Aliens and future scenarios, but couldn't care less about spaceships and laser battles? Zell is the guy for you. He's hot, he's good in bed, and he's out to save the world he lives in. He will risk his life willingly for those he loves and for what he believes in - and he takes a lot of damage for his convictions. Ready for a hot adventure on a planet that was terraformed and colonized by humans and then taken over by aliens?  Zell finds himself in the hands of Diles, as his Tribe call the aliens who conquered their world.
Fortunately, his Master is not one of the sadistic ones that he has heard about. And the young woman Zell is supposed to train as a bed pet turns out to be smart, brave and inventive. However, his Master intends to gift him to a Dile who turns out to be the worst possible owner - and who becomes a formidable enemy. Soon, Zell's Master also finds out that it is impossible to quench the spirit of a Wild One. Best reading order for the Franssis Four Chronicles:DecoyCaptiveFugitiveCatalystFulcrumFlux
